GENERAL DESCRIPTION

 

Comfort Flex 

chiller units are built with control and design in 

mind,  assembled  with  technically  specialized  control 
software. Some of our features are in house production of all 
piping  and  wiring,  scroll  type  compressors,  new  generation 
evaporators,  air  cooled  condensers,  optional  hydraulic 
components,  and  several  safety  and  security  protections. 
Our  units  are  ecofriendly  and  operate  with  R-410A 
refrigerant.

 

ELECTRICAL COMPONENTS 

All  units  are  equipped  with  a  control  panel,  security  anti-
theft devices, internal and external overheating protection, 
compressor  drive  protection,  flow  protection,  freezing 
protection  and  electrical  failure  protection.  The  control 
panel has LED operation indicating lights.

 

EQUIPMENT 

Fully Factory assembled, and individually run tested with all 
required piping, wiring, and controls for operation. 

HYDRAULIC COMPONENTS (OPTIONAL) 

WATER PUMP 

The drive in the water pump is TEFC (Totally Enclosed 

Fan Cooled) and has anti-corrosive coating on the 

housing.

 

MODULE 

 

Steel base, anti-corrosive painted steel panels. Easy Access 

for maintenance without compromising the unit´s stability. 

 

CONTROL 

The  control  unit  allows  the  connection  of  the  unit  to  the 
INTERNET,  and  allows  the  user  to  visualize  all  the  unit’s 
operating information, such as variable graphics, tendencies 
cycle time, diagnosis of components, alarms, etc. Access to 
this  information  renders  a  more  efficient  operation  and 

system control.

 

 

 

COMPRESSORS 

Two stage Scroll type hermetic compressors.

 

CONDENSERS 

High  efficiency  microchannel  with  optional  anti-corrosive 
coating.

 

EVAPORATORS 

Compact  Plate  Heat  exchangers  with  thermally  isolated 
hydraulic refrigerant pipes and connections.

 

FANS 

Low vibration and noise Axial Fans. 

REFRIGERATION CONTROLS 

The units are equipped with solenoid valves, expansion 

valves, dehydrator, and service valves.
